The SEALMASTER FB series is a flange housing with an insert bearing, supplied as a mounted unit that bolts to a flat surface. It supports and guides shafts in equipment where the mounting point must stay compact and rigid. MR Industrial Accessories supplies this line and can help you match the right variant to your application.
Reading the code: the prefix FB denotes the flange housing with insert bearing. The number that follows gives the shaft diameter the unit fits, and the trailing letter R in codes such as FB-20R and FB-32R identifies the insert version. For a quote, send the full code from the equipment tag or the bearing plate.
Typical installations include conveyors, mixers, fans, pumps, and agricultural or food processing machinery that call for a flange support with fixed alignment. Plants in food, cement, mining and aggregate processing also rely on this type of mounting when maintenance needs to stay simple.
Selection depends on shaft diameter, fixing method and the working environment. The insert seal determines how well the unit handles dust and moisture; for washdowns or heavy contamination, extra protection is recommended. Mount on a flat, clean surface, tighten bolts in a cross pattern, and check alignment to avoid axial loads.
Flange housings with insert bearings can be interchanged between brands when flange dimensions, shaft diameter and fixing system match. During replacement, compare the overall height and the bolt hole spacing. If anything is unclear, send a photo or the assembly code and we will point you to a compatible alternative.
MR Industrial Accessories supplies the SEALMASTER line and also manufactures split plummer block housings and sheaves. To request the FB housing with insert bearing, message us on WhatsApp or email with code FB-20R or FB-32R and we will quote promptly.

Frequently asked questions
- What does FB indicate in this housing?
- FB is the flange housing series with insert bearing. The number after it is the shaft diameter, and the final letter marks the insert version. Send the complete code and we will quote the exact variant.
- How do I decide between an FB housing and another housing type?
- It comes down to how the unit is fixed and the space available. The FB bolts to a flat surface through its flange. If your equipment uses a pillow block or take-up housing, another line is a better fit. Tell us how it is mounted and we will guide you.
- Are SEALMASTER housings compatible with other brands?
- Yes, provided the flange dimensions, shaft diameter and fixing system match. When replacing, compare the bolt hole spacing and overall height. Send those data and we will indicate the equivalent.
